llvm-objdump - LLVM’s object file dumper¶
SYNOPSIS¶
llvm-objdump [commands] [options] [filenames…]
DESCRIPTION¶
The llvm-objdump utility prints the contents of object files and final linked images named on the command line. If no file name is specified, llvm-objdump will attempt to read from a.out. If - is used as a file name, llvm-objdump will process a file on its standard input stream.
COMMANDS¶
At least one of the following commands are required, and some commands can be combined with other commands:
-
-d
,
-disassemble
¶
Display assembler mnemonics for the machine instructions. Disassembles all text sections found in the input file(s).
-
-D
,
-disassemble-all
¶
Display assembler mnemonics for the machine instructions. Disassembles all sections found in the input file(s).
-
-help
¶
Display usage information and exit. Does not stack with other commands.
-
-r
¶
Display the relocation entries in the file.
-
-s
¶
Display the content of each section.
-
-section-headers
¶
Display summaries of the headers for each section.
-
-t
¶
Display the symbol table.
-
-version
¶
Display the version of this program. Does not stack with other commands.

llvm-objdump supports the following options:
-
-arch
=<architecture>
¶ Specify the architecture to disassemble. see
-version
for available architectures.
-
-cfg
¶
Create a CFG for every symbol in the object file and write it to a graphviz file (Mach-O-only).

=<string>
¶ Use .dSYM file for debug info.
-
-g
¶
Print line information from debug info if available.
-
-m

-mattr
=<a1,+a2,-a3,...>
¶ Target specific attributes.
-
-mc-x86-disable-arith-relaxation
¶
Disable relaxation of arithmetic instruction for X86.
-
-stats
¶
Enable statistics output from program.
-
-triple
=<string>
¶ Target triple to disassemble for, see
-version
for available targets.
-
-x86-asm-syntax
=<style>
¶ When used with the
